Add destination-buffer pitch as argument to drm_fb_swab(). Done for consistency with the rest of the interface. v2: * update documentation (Noralf) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Tested-by: Noralf Trønnes <noralf@tronnes.org> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20211110103702.374-4-tzimmermann@suse.de
